This new understanding of processes on Europa would not have been possible without the foundation of the last 20 years of observations over Earth's ice sheets and floating ice shelves. ↗
Ice shelves in general have episodic carvings and there can be large icebergs breaking off - I'm talking 100km or 200km long - every 10 or 20 or 50 years. ↗
The only thing I have done religiously in my life is keep a journal. I have hundreds of them, filled with feathers, flowers, photographs, and words - without locks, open on my shelves. ↗
The society of dead authors has this advantage over that of the living: they never flatter us to our faces, nor slander us behind our backs, nor intrude upon our privacy, nor quit their shelves until we take them down. ↗
